Description:	Natural ventilation in terrace houses is of primary importance especially in a tropical country with hot and humid climate like Malaysia. The aim of this study is to determine the effect of balcony to enhance natural ventilation and also proved that the balcony could be used as transitional space to control and induce the outdoor air flow into indoor spaces of terrace houses in Malaysia. The main objective in this study is to find the relevance of the balcony design in the terrace housing context of Malaysia. This study mainly employs experimental research design with the research consisting of two methods. The first method considered previous studies conducted and the second used a computational analysis with IES Virtual Environment 6.0 software, MacroFlo simulation and MicroFlo CFD simulation in order to accurately and quickly assess the natural ventilation design.In this study, 3 models of terrace houses with the same plan are considered within the capital city of Malaysia, Kuala Lumpur. Model A consist of a terrace house with a balcony and a wing wall, model B consist of a terrace house with a balcony but without a wing wall and model C consist of a terrace house without a balcony. The study also analyzed two type of balcony design introduced in Model A and model B. Additional study examined the effect of wing wall to improve airflow direction into terrace houses. The base for weather data in this study is ASHRAE. ASHRAE applied data’s such as air temperature, relative humidity, wind speed and wind direction in the IES software and analyzed it with ApacheHvac. Results of MicroFlo CFD simulation showed the air velocity and MacroFlo simulation showed measured volume flow rate, air temperature, relative humidity, natural vent gain and all the variables of natural ventilation in the terrace house model. Unlike previous studies, the primary finding indicated that using the balcony in terrace houses in warm and humid climate like Malaysia does not contribute significantly to the increase in natural ventilation into the building. The second finding indicated that the air velocity inside terrace houses is low for most of the times and balcony does not significantly affect the air temperature inside the terrace houses. The utilizing of wing wall in a balcony design could not improve airflow direction but it can assist in decreasing the negative effect of using balcony without the wing wall in place. These findings could assist in further studies and future research in the area of sustainable houses.,Master of Science,Certification of Master's / Doctoral Thesis" is not available"
